How to start investing in stocks

To invest in stocks, you open a brokerage account with a company that buys and sells shares on your behalf, deposit money into that account, and then place orders to buy individual stocks or stock funds. The process takes about 15 minutes online. You do not need a large amount of money to begin — most brokers let you start with $1 or $100, though some funds have minimums of $500 to $3,000. The real decision is not how to open the account but what to buy once it is open, because that choice determines your risk and your potential return.

As a homeowner, you already understand that money sitting still loses value to inflation. Stocks are one way to make your money work. They are not the only way — bonds, real estate investment trusts, and high-yield savings accounts all exist — but stocks have historically returned more over long periods than other options available to ordinary people. The trade-off is that stocks move up and down in value in the short term, sometimes sharply, and you can lose money if you sell at the wrong time.

Key Takeaways

  • You need a brokerage account to buy stocks; opening one takes 15 minutes and requires a Social Security number, proof of address, and a bank account to fund it.
  • Most people new to investing should start with low-cost index funds or target-date funds rather than picking individual stocks, because these spread your money across many companies and reduce the damage from a single bad choice.
  • The money you invest should be money you will not need for at least five years, because stocks can drop sharply in the short term and recovering from a loss takes time.
  • Your age and how soon you need the money matter more than market conditions right now — a 30-year-old can ride out drops that would hurt a 65-year-old.

Choosing a brokerage and opening an account

A brokerage is a company licensed to buy and sell stocks on your behalf. The major ones are Fidelity, Vanguard, Charles Schwab, E*TRADE, and Robinhood, but dozens of others exist. They all charge little or nothing to open an account and place trades — the money they make comes from other sources, like lending out your shares or charging for premium services you do not need.

To open an account, you will need your Social Security number, a government-issued ID, proof of your current address (a utility bill or lease works), and a bank account to link for deposits. The brokerage will ask you questions about your income, employment, and investment experience. These are regulatory requirements, not attempts to exclude you. Answer honestly. You will then choose between a regular taxable account (called a brokerage account) or a tax-advantaged account like a Roth IRA or traditional IRA. If you are not sure, start with a regular brokerage account — it has no contribution limits and no rules about when you can withdraw money.

Once your account is open and you have deposited money, you are ready to buy. Most brokerages let you place an order in seconds through their website or app. You search for a stock or fund by its ticker symbol (a short code like AAPL for Apple or VTI for a Vanguard index fund), enter how many shares you want, and confirm the order. The trade executes immediately during market hours, usually within seconds.

Understanding stocks versus stock funds

A stock is a small piece of ownership in a single company. When you buy one share of Apple, you own a tiny fraction of Apple. If Apple does well, the stock price rises and you can sell it for more than you paid. If Apple struggles, the price falls. Picking individual stocks means you are betting that you can predict which companies will do well, which is hard even for professionals.

A stock fund (also called a mutual fund or exchange-traded fund) is a basket of many stocks bundled together. An index fund holds all the stocks in a particular index — for example, the S&P 500 index fund holds shares in 500 large U.S. companies. When you buy one share of an S&P 500 index fund, you own a tiny piece of all 500 companies at once. If one company fails, it barely dents your fund because the other 499 are still there. This spreading of risk is called diversification.

Most people new to investing should start with index funds or target-date funds rather than individual stocks. A target-date fund automatically adjusts its mix of stocks and bonds as you get closer to retirement, so you do not have to think about rebalancing. The fees are low — often 0.05% to 0.20% per year — and you get the benefit of owning hundreds of companies with one purchase. Individual stocks are more exciting and can produce higher returns, but they also require more research and carry more risk of loss.

How much money you need and where it comes from

You can start investing with as little as $1 at some brokerages, though many funds have minimum investments of $500 to $3,000 for the first purchase. After that, you can usually add money in smaller amounts. The real question is not the minimum but where the money should come from: it should come from money you have already saved and do not need for at least five years.

If you are still paying off credit card debt or have less than three months of expenses in an emergency fund, investing in stocks is not the right move yet. Stocks can drop 20%, 30%, or more in a single year. If you need that money in two years and the market is down, you will be forced to sell at a loss. The money you invest should be money you can afford to leave alone through market ups and downs.

Many people invest through automatic deposits — setting up your brokerage to pull $100 or $500 from your checking account every month. This removes the emotion from the decision and means you buy more shares when prices are low and fewer when prices are high, which over time tends to improve returns. It also makes investing a habit rather than a one-time event.

Your age and time horizon matter more than current market conditions

The single biggest factor in how you should invest is how long until you need the money. A 30-year-old investing for retirement can afford to own 90% stocks and 10% bonds because even if stocks crash tomorrow, there are 35 years for them to recover. A 65-year-old who needs the money in five years should own much less in stocks — maybe 40% stocks and 60% bonds — because there is not enough time to recover from a major drop.

This is why target-date funds are useful: a target-date 2050 fund assumes you will retire around 2050 and automatically holds mostly stocks now (because you have time) and gradually shifts to more bonds as 2050 approaches. You do not have to guess what the right mix is.

Market conditions right now — whether stocks are up or down, whether the news is good or bad — should not change your decision to invest. Trying to time the market (buying when you think it will go up and selling when you think it will go down) is a losing game even for professionals. A better approach is to invest regularly regardless of conditions, which means you buy at all prices and benefit from the long-term trend.

Tax considerations for different account types

A regular brokerage account has no contribution limits and no rules about when you can withdraw money, but you pay taxes on any gains when you sell. If you buy a stock for $1,000 and sell it for $1,500, you owe taxes on the $500 gain. The tax rate depends on how long you held it — less than a year is taxed as ordinary income, more than a year is taxed at a lower "long-term capital gains" rate.

A Roth IRA lets you contribute up to $7,000 per year (as of 2024, though this amount changes). You pay taxes on the money before it goes in, but then it grows tax-free and you can withdraw it tax-free in retirement. There are income limits for who can contribute to a Roth IRA, and you cannot withdraw the earnings before age 59½ without a penalty (though you can withdraw your contributions anytime).

A traditional IRA lets you contribute up to $7,000 per year and deduct that contribution from your taxes in the year you make it. The money grows tax-free, but you pay taxes on withdrawals in retirement. If your employer offers a 401(k), that is another tax-advantaged account with higher contribution limits.

If you are new to investing, start with a regular brokerage account to keep things simple. Once you understand how investing works, you can open a Roth IRA or take advantage of an employer 401(k) to reduce your taxes.

Common mistakes to avoid when starting out

The most common mistake is investing money you will need soon. The second is buying individual stocks based on a tip or a news story rather than research. The third is checking your account balance constantly and panicking when it drops. Markets go down regularly — sometimes 10%, sometimes 20% or more — and that is normal. If you panic and sell during a drop, you lock in the loss. If you stay invested, you usually recover.

Another mistake is paying high fees. Some brokerages and funds charge 1% or more per year, which sounds small but compounds over decades. A $10,000 investment in a fund charging 1% per year will have roughly $2,000 less after 30 years than the same investment in a fund charging 0.1% per year, assuming the same returns. Use low-cost index funds and avoid actively managed funds unless you have a specific reason.

Finally, do not try to time the market or chase performance. If a stock or fund had great returns last year, that does not mean it will have great returns this year. Stick to a simple plan — invest regularly in low-cost index funds matched to your age and time horizon — and ignore the noise.

Frequently Asked Questions

Do I need a lot of money to start investing in stocks?

No. Most brokerages let you open an account with $1 or $100. Some funds have minimums of $500 to $3,000 for the first purchase, but after that you can add smaller amounts. The real requirement is that the money should be money you will not need for at least five years.

What is the difference between a stock and a stock fund?

A stock is ownership in one company. A stock fund is a basket of many stocks. If you own one stock and that company fails, you lose your money. If you own a fund and one company fails, the other companies in the fund cushion the loss. Most people new to investing should start with funds.

Should I invest if the stock market is down right now?

Yes. When the market is down, stocks are cheaper, so your money buys more shares. Over long periods, buying at all prices — high and low — tends to produce better results than trying to guess when to buy and sell. If you have 10 or more years until you need the money, current market conditions should not change your decision.

Can I lose all my money investing in stocks?

If you own a single stock in a company that goes bankrupt, yes. If you own a diversified index fund, it is extremely unlikely — the fund would have to hold hundreds of companies that all failed at once, which has never happened in modern history. This is why diversification matters.

What should I do if the stock market crashes after I invest?

Do nothing. Market crashes are normal and temporary. If you sell during a crash, you lock in the loss. If you stay invested, you usually recover within months or a few years. The longer your time horizon, the less a crash matters.
